HYDROCARBON-FURNACE.

SPECIFICATION forming part of Letters Patent No. 244,081, dated July 12, 1881.

Application filed April 25, 1881. (No model.)

To all whom it may concern Be it known that I, HERRMAN S. SARONI, of the city of St. Paul, county of Ramsey, and State of Minnesota,have invented certain new and useful Improvements in Hydrocarbon- Furnaces, of which the following is a specification,reference.being had to the accompanying drawings, forming part of the same, in which- Figure 1 is a vertical section of a steamboiler with myimproved attachments for generating heat connected therewith. Fig. 2 is a top view of part of my improvement; and Fig. 3 is a sectional view, on a somewhat enlarged scale, of the same.

My invention relates to the construction and arrangement of a hydrocarbon-furnace equally adapted to vertical or horizontal tubular or flue boilers, or to any other purpose where heat is required.

A represents a steam-boiler with the tubular flues A, the fire-box A the steam-dome A the fire-bridge A and the combustionchamber A.

B is a steam-superheater of any suitable form" or material, arranged within the fire-box A preferably along the sides thereof, connected at B with the steam-dome A provided with the reducing-valve D, and terminating with the nozzle 0.

E is a tubular chamber with branches e 6, provided with perforations f f, which is more distinctly shown in Fig. 2, and into which the nozzle 0 enters, likewise the nozzles F and G. It is also provided with the larger apertures H I and the trap K.

The nozzle F is provided with a spindlevalve, L, which regulates the size of the opening of the nozzle F, so as to adapt it to the use of heavier or lighter fluids, diminishing it for the former and increasing it for the latter, and connects through the valve M and tube N with the tank 0.

The nozzle Gr connects with the coil-retort P, the tube Q, the valve R, and the tank S. At T a branch tube runs to the valve U, and thence to the burner V.

The operation of the described apparatus is as follows: Water being supplied to the boiler A, and liquid hydrocarbon to the tanks 0 and S, the former being either sufficiently elevated to give the requisite pressure to the fluid issuing at the nozzle G, or being provided with the means of giving aerostatic pressure to the fluid contained therein, the valve U is opened sufflciently to flll the cup attached to the burner V, which latter may be of any form used for the production of heat. The cup being filled, the valve U is closed and the fluid in the cup ignited. When the burnerV is heated sufficiently the valve N is again opened, and the flame of the burner will heat the coil-retort P intensely. The valve R is now opened, and the pressure in the tank S will force the fluid through the retort 1?, where it is quickly converted into vapor, and through the nozzle G into the chamber E, absorbing through the apertures H and I a certain quantity of atmospheric air, and issuing through the perforations ff as a vivid flame, which can be controlled by the valve R. That a retort of any form suitable for the purpose can be used is evident; but I prefer the coil shape 1?, because it operates so quickly. When steam of sufficient pressure has thus been generated in the boiler A (ten pounds being generally sufficient) the valve D is opened simultaneously with the valve M. The steam now passes into the superheater B, thence through the nozzle 0 into the chamber E, carrying with it, in the form of a fine spray, the hydrocarbon from the tank 0, and issuing through the perforations ff as flame of intense heat. The valves M and U are now closed, leaving the apertures H and I free to the induced currents of air caused by the passage of the steam to mix with the steam and hydrocarbon spray in the chamber E.

The use of the reducing-valve D is to maintain an even pressure in the superheater and the nozzle 0, although the pressure in the boiler may vary.

The trap K, although not strictly necessary, by allowing the condensed steam to escape, will greatly facilitate the lighting of the fire when steam has been raised in an auxiliary boiler, as may be the case when the main furnace is to be used for purposes other than the generating of steam.

In order to save waste of fuel, and to obviate the danger of the fluids trickling down the lower (the fluid) nozzle, I have departed from the customary rectangular form of the atomizer and placed the nozzles G and F at a slightly acute angle, at the same time beveling the mouths of the nozzles toward the chamber E.

So much in my process depends upon the form and relative position of the nozzles O and F that I have enlarged the drawing of that part of my inventionin Fig. 3, and I draw particular attention to the fact that with the mouth of the nozzles beveled and the angle formed by the two nozzles slightly acute I have obtained the best results, consisting of more perfect atomization of the fluid, combined with greater economy.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the nozzles O and F with the perforated chamber H I and the chamber E, as and for the purpose herein set forth.

2. The combination, with a fire-box, of a superheater located in said fire-box, a steampipe, B leading from a boiler through the reducing-valve D to the superheater B and terminatin g with the nozzle 0, the nozzle F, with valve L, the tube N, the valve M, the tank 0, the chamber E, with branches e, and perforations ff, and apertures H I, and the trap K, as and for the purpose herein described.

3. The combination of the chamber E, its branches 0 0, its perforations ff, and the apertures H I, with the nozzle G, the retort P, the valve R, the tube Q, and the tank S, all as and for the purpose herein described.

4. The combination of the chamber E, its perforations f f, the apertures H I, the nozzle G, the retort P, the tube Q, the valve R, and the tank S, with the burner V, the tube T T, and the valve U, all as and for the purpose herein described.

5. The combination, with a fire-box, of a superheater located 'in said fire-box, a steampipe, B leading from a steam-boiler through the reducing-valve D to the superheater B, terminating with the nozzle 0, the nozzle F, valve L, tube N, valve M, tank 0, chamber E, perforations ff, apertures H I, and trap K, with the nozzle G, the retort l, the tube Q, the valve R, the tank S, the tube T, the valve U, and the burner V, all as and for the purpose herein described.

Witness my hand this th day of April, 1881.
